Have you ever wondered why someone doesn’t write a really interesting book about shoemakers or Idaho or health inspectors? When I worked at the bookstore I used to get questions like this all the time. Usually, I was forced to stare blankly for a moment before performing a futile search on the computer. But every once in while, someone would ask, “Are there any really good books about the geology of North America?” And my eyes would light up and I would say, “Yes!” The same was true if they asked for books about merchant marines, Alaska, or canoes. John McPhee has the ability – which I prize as a reader – to write engagingly about any subject, and Founding Fish is no exception. In this case, the subject is the American Shad. The fish is prized by anglers and gourmands and pops in and out of American history. But this is not “the cultural history of American Shad” (are we tired of these “cultural history of…” books yet?”) Instead he weaves history with science as well as plenty of personal observation. The myriad digressions are like seams of precious metal. McPhee’s world is populated with fascinating characters – ichthyologists, shad dart makers, and a seine fisherman from the Bay of Fundy. If you have a taste for non-fiction and would like a book that is diverting and pleasurable (rather than “hard-hitting” and topical) try reading John McPhee.Spotted on the el: The Rule of Four by Ian Caldwell and Dustin ThomasonNew list: The Economist best of the year.
